The Enemy Within

[ MUSIC ]

THAT SHOULD MAKE A GOOD SPECIMEN.

TEMPERATURE'S STARTING TO DROP.

YEAH.

AT NIGHT, IT GETS DOWN TO 120 DEGREES BELOW ZERO.

THAT'S NIPPY.

HEY!

WHAT HAPPENED?

I FELL OFF THAT BANK, SIR.

CUT MY HAND.

LET'S SEE.

GET BACK TO THE SHIP. REPORT TO THE SICK BAY.

YES, SIR.

[ ELECTRONIC BEEPING ]

GEOLOGICAL TECHNICIAN FISHER, READY TO BEAM UP.

[ MUSIC ]

ALL RIGHT. LOCKED ONTO YOU.

[ BEEPING ]

ENERGIZE.

[ BEEPING ]

CADJULAR ENGAGEMENT.

WHAT HAPPENED?

I TOOK A FLOP.

ONTO WHAT?

I DON'T KNOW. SOME KIND OF YELLOW ORE.

MAGNETIC.

DECONTAMINATE THAT UNIFORM.

YES, SIR.

THAT ACTED LIKE A BURNOUT.

[ WHISTLE ]

CAPTAIN KIRK READY TO BEAM UP.

JUST ONE MOMENT, CAPTAIN.

[ WHISTLE ]

IT CHECKS OUT OKAY NOW.

YOU BETTER GO GET A SYNCHRONIC METER SO WE CAN DOUBLE CHECK.

YES, SIR.

[ WHISTLE ]

ALL RIGHT, CAPTAIN. LOCKED ONTO YOU.

[ WHISTLE ]

[ BEEPS ]

ARE YOU ALL RIGHT, CAPTAIN?

I'M ALL RIGHT. JUST A LITTLE DIZZY.

HERE, LET ME GIVE YOU A HAND.

I CAN'T GET THROUGH THERE.

NOTHING SERIOUS.

DON'T LEAVE THE TRANSPORTER ROOM UNATTENDED.

WILSON WILL BE RIGHT BACK, SIR.

[ WHISTLE ]

[ BEEPS ]

[ SINISTER MUSIC ]

[ MUSIC ]

SPACE, THE FINAL FRONTIER.

THESE ARE THE VOYAGES OF THE STARSHIP, ENTERPRISE.

ITS FIVE-YEAR MISSION, TO EXPLORE STRANGE NEW WORLDS.

TO SEEK OUT NEW LIFE AND NEW CIVILIZATIONS.

TO BOLDLY GO WHERE NO MAN HAS GONE BEFORE.

[ MUSIC ]

CAPTAIN'S LOG, STAR DATE 1672.1.

SPECIMEN GATHERING MISSION ON PLANET ALPHA 177.

UNKNOWN TO ANY OF US DURING THIS TIME,

A DUPLICATE OF ME, SOME STRANGE ALTER EGO,

HAD BEEN CREATED BY THE TRANSPORTER MALFUNCTION.

[ MUSIC ]

[ BEEPING ]

CAPTAIN?

ARE YOU ALL RIGHT, SIR?

CAN I GIVE YOU A HAND, SIR?

CAPTAIN?

BRIDGE TO ALL DECKS.

SECTION THREE OFFICERS, PLEASE CHECK COMMUNICATION LINES.

THANK YOU.

UH, IT MIGHT PROFIT YOU TO LET DR. MC COY

GIVE YOU THE ONCE OVER.

ALL RIGHT, ENGINEER. I'LL HAVE MY ENGINES LOOKED TO.

SHIP'S MANIFESTS, SIR.

I THINK THEY'RE IN ORDER NOW.

THANK YOU, YEOMAN.

I'VE CHECKED--

THAT'S ALL.

YES, SIR.

[ MUSIC ]

YOU PICKED A GOOD DAY, FISHER. BUSINESS HAS BEEN LOUSY.

WHAT DID YOU DO, TAKE A FALL ON PURPOSE,

SO YOU COULD GET A LITTLE VACATION?

SAURIAN BRANDY.

UM, BACK TO DUTY STATUS, FISHER.

I HAVE NO SYMPATHY FOR CLUMSINESS.

YES, SIR.

THE HAND'S MUCH BETTER, SIR.

WHAT CAN I DO FOR YOU, JIM?

I SAID GIVE ME THE BRANDY!

[ MUSIC ]

[ DOOR KNOCK ]

YEAH?

MR. SPOCK.

COME IN.

YES, MR. SPOCK, WHAT IS IT?

IS THERE SOMETHING I CAN DO FOR YOU, CAPTAIN?

LIKE WHAT?

WELL, DR. MC COY SEEMED TO THINK THAT I SHOULD CHECK ON YOU.

THAT'S NICE.

COME ON, SPOCK. I KNOW THAT LOOK. WHAT IS IT?

WELL, OUR GOOD DOCTOR SAID THAT YOU WERE ACTING LIKE A WILD MAN,

DEMANDED BRANDY.

[ LAUGH ]

OUR GOOD DOCTOR'S BEEN PUTTING YOU ON AGAIN.

HMM.

WELL, IN THAT CASE,

IF YOU'LL EXCUSE THE INTRUSION, CAPTAIN,

I'LL GET BACK TO MY WORK.

I'LL TELL HIM YOU WERE PROPERLY ANNOYED.

CAPTAIN.

WHAT IS IT, SCOTTY?

TRANSPORTER BREAKDOWN, SIR.

CONTINUE CIRCUIT TESTING.

WE BEAMED UP THIS ANIMAL. AND, WELL, LOOK FOR YOURSELF.

IT'S IN THIS SPECIMEN CASE.

YES?

A FEW SECONDS AFTER THEY SENT THIS ONE UP

THROUGH THE TRANSPORTER, THAT DUPLICATE APPEARED.

EXCEPT IT'S NOT A DUPLICATE. IT'S AN OPPOSITE.

TWO OF THE SAME ANIMAL, BUT DIFFERENT.

ONE GENTLE, THIS. ONE MEAN AND FIERCE, THAT.

SOME KIND OF SAVAGE FEROCIOUS OPPOSITE.

CAPTAIN, WE DON'T DARE SEND MR. SULU AND THE LANDING PARTY UP.

IF THIS SHOULD HAPPEN TO A MAN--

OH, MY.

[ MUSIC ]

OH, CAPTAIN. YOU STARTLED ME.

IS THERE SOMETHING THAT YOU--

CAN I HELP YOU, CAPTAIN?

JIM WILL DO HERE, JANICE.

OH.

YOU'RE TOO BEAUTIFUL TO IGNORE. TOO MUCH WOMAN.

WE'VE BOTH BEEN PRETENDING TOO LONG.

-STOP PRETENDING-- -[ SCREAM ]

LET'S STOP PRETENDING.

COME HERE, JANICE. DON'T FIGHT ME.

DON'T FIGHT ME, JANICE.

CAPTAIN!

JUST A MINUTE, JANICE.

JUST A MINUTE!

NO! NO!

AAH.

[ SCREAMING ]

CALL MR. SPOCK! CALL MR. SPOCK!

GEOLOGICAL TECHNICIAN FISHER. DECK 12, SECTION--

ME? MY YEOMAN SAID THAT?

I'VE BEEN RESTING HERE SINCE YOU LEFT ME.

ALONE, MR. SPOCK.

CAPTAIN, DR. MC COY REPORTS THAT YOU DEMANDED THIS BRANDY

IN SICK BAY AND LEFT WITH IT.

I FOUND THIS BOTTLE IN YEOMAN RAND'S QUARTERS.

NOT TRUE. I HAVEN'T BEEN TO THE SICK BAY.

LET'S FIND OUT WHAT'S GOING ON.

SICK BAY.

[ MUSIC ]

THEN HE KISSED ME. AND HE SAID THAT WE--

THAT HE WAS THE CAPTAIN. AND HE COULD ORDER ME.

I DIDN'T KNOW WHAT TO DO.

AND YOU MENTIONED THE FEELINGS WE'VE BEEN HIDING.

AND YOU STARTED TALKING ABOUT US--

US?

WELL, HE IS THE CAPTAIN. I COULDN'T JUST--

YOU STARTED HURTING ME.

I HAD TO FIGHT YOU AND SCRATCH YOUR FACE.

YEOMAN?

LOOK AT ME.

LOOK AT ME. LOOK AT MY FACE.

ARE THERE ANY SCRATCHES?

I WAS SURE I SCRATCHED YOU.

I WAS FRIGHTENED. MAYBE--

YEOMAN, I WAS IN MY ROOM. IT WASN'T ME.

SIR, FISHER SAW YOU, TOO.

FISHER--

IF IT HADN'T BEEN-- I CAN UNDERSTAND.

I DON'T WANT TO GET YOU INTO TROUBLE.

I WOULDN'T HAVE EVEN MENTIONED IT.

IT WASN'T ME.

IT WAS YOU, SIR.

DO YOU KNOW WHAT YOU'RE SAYING?

YES, SIR. I KNOW WHAT I'M SAYING.

BACK TO THAT BED, BUCKO. COME ON, LET'S GO.

YOU CAN GO NOW, YEOMAN.

THERE'S ONLY ONE LOGICAL ANSWER.

WE HAVE AN IMPOSTER ABOARD.

[ MUSIC ]

CAPTAIN'S LOG, STAR DATE 1672.9.

ON THE PLANET'S SURFACE,

TEMPERATURES ARE BEGINNING TO DROP.

OUR LANDING PARTY THERE IN GROWING JEOPARDY.

DUE TO THE MALFUNCTION OF THE SHIP'S TRANSPORTER,

AN UNEXPLAINED DUPLICATE OF MYSELF DEFINITELY EXISTS.

HOW DID ALL THIS HAPPEN?

I DON'T KNOW, SIR.

BUT WHEN FISHER CAME UP, HIS SUIT WAS COVERED

WITH A SOFT YELLOW ORE.

IT HAD HIGHLY UNUSUAL PROPERTIES.

IT MAY HAVE CAUSED AN OVERLOAD. I CAN'T TELL.

NOT YET.

DOES THE TRANSPORTER WORK AT ALL?

YES, SIR.

BUT WE DON'T DARE BRING UP THE LANDING PARTY.

THEY MIGHT BE DUPLICATED LIKE THIS ANIMAL.

HOW LONG WILL IT TAKE YOU TO FIND THE TROUBLE?

CAN'T SAY, SIR.

WE JUST CAN'T LEAVE THOSE FOUR MEN DOWN THERE.

IT'S GETTING DARK. THEY'LL DIE.

THE SURFACE TEMPERATURE OF THAT PLANET GOES DOWN TO

120 DEGREES BELOW ZERO AT NIGHT.

WE'RE DOING EVERYTHING WE CAN, SIR.

YES, I KNOW, SCOTTY.

ABOUT YOUR DOUBLE, CAPTAIN.

YES. UH--

YES.

WE'LL HAVE TO FIND HIM.

SEARCH PARTIES, MR. SPOCK. ORGANIZE SEARCH PARTIES.

WE CAN'T TAKE A CHANCE ON KILLING IT.

WE HAVE NO PREVIOUS EXPERIENCE,

NO WAY OF KNOWING WHAT WOULD HAPPEN TO YOU.

THAT'S RIGHT. WE DON'T KNOW.

BUT THE MEN WILL HAVE TO BE ARMED.

THE MEN ARE TO BE ARMED WITH THE PHASERS LOCKED--

I REPEAT LOCKED-- ON SETTING NUMBER ONE.

THERE CAN'T BE ANY CHANCE OF HIM BEING KILLED.

HE'S TO BE TAKEN WITHOUT-- IF THE MEN ARE FORCED TO FIRE,

HE CAN'T BE KILLED.

HOW SHOULD WE EXPLAIN IT TO THEM, CAPTAIN?

THE SEARCH PARTIES ARE TO CAPTURE YOU?

TELL THEM--

THE SEARCH PARTIES, CAPTAIN?

YES.

I'LL MAKE AN ANNOUNCEMENT TO THE ENTIRE CREW.

TELL THEM WHAT HAPPENED.

IT'S A GOOD CREW. THEY DESERVE TO KNOW.

CAPTAIN, NO DISRESPECT INTENDED. BUT YOU MUST SURELY REALIZE

YOU CAN'T ANNOUNCE THE FULL TRUTH TO THE CREW.

YOU'RE THE CAPTAIN OF THIS SHIP.

YOU HAVEN'T THE RIGHT TO BE VULNERABLE

IN THE EYES OF THE CREW.

YOU CAN'T AFFORD THE LUXURY OF BEING ANYTHING

LESS THAN PERFECT.

IF YOU DO, THEY LOSE FAITH, AND YOU LOSE COMMAND.

YES. I DO KNOW THAT, MR. SPOCK.

WHAT I DON'T KNOW IS WHY I FORGOT THAT JUST NOW.

[ MUSIC ]

MR. SPOCK,

IF YOU SEE ME SLIPPING AGAIN, YOUR ORDERS--

YOUR ORDERS ARE TO TELL ME.

UNDERSTOOD, CAPTAIN.

[ MUSIC ]

CAPTAIN'S LOG, STAR DATE 1673.1.

SOMETHING HAS HAPPENED TO ME.

SOME HOW IN BEING DUPLICATED, I HAVE LOST

MY STRENGTH OF WILL.

DECISIONS ARE BECOMING MORE AND MORE DIFFICULT.

THIS IS THE CAPTAIN SPEAKING.

THERE'S AN IMPOSTER ABOARD THE SHIP.

A MAN WHO LOOKS EXACTLY LIKE ME AND IS PRETENDING TO BE ME.

THIS MAN IS DANGEROUS.

UTMOST CAUTION IS TO BE OBSERVED.

ALL CREW MEMBERS ARE TO ARM THEMSELVES.

THE IMPOSTER MAY BE IDENTIFIED BY SCRATCHES ON HIS FACE.

REPEAT.

THE IMPOSTER MAY BE IDENTIFIED BY SCRATCHES ON HIS FACE.

SECTION CHIEFS, ASSIGN PERSONNEL TO THE SEARCH.

ALL SEARCH PARTIES REPORT TO MR. SPOCK FOR ASSIGNMENT.

SOMETHING?

ABOUT THE PHASER WEAPONS TO BE SET FOR STUNNING FORCE

AND LOCKED--

OH, YES. YES.

ALL HAND PHASERS MUST BE SET ON BASE CYCLE,

STUNNING FORCE.

THE IMPOSTER IS NOT TO BE INJURED.

USE MINIMUM FORCE. REPEAT--

I'M CAPTAIN KIRK!

--THE IMPOSTER IS NOT TO BE INJURED.

I'M CAPTAIN KIRK.

I'M CAPTAIN KIRK!

I'M CAPTAIN KIRK!

[ MUSIC ]

I'M CAPTAIN KIRK.

WILSON.

SIR?

WILSON, GIVE ME YOUR PHASER.

YES, SIR.

HOW YOU BEEN?

FINE, SIR.

[ MUSIC ]

HOW'S IT GOING DOWN THERE, MR. SULU?

IT'S ALREADY TWENTY DEGREES BELOW ZERO.

CAN'T EXACTLY CALL IT BALMY.

ISN'T THERE ANY WAY WE CAN HELP THEM?

THERMAL HEATERS WERE TRANSPORTED DOWN.

THEY DUPLICATED.

THEY WON'T OPERATE.

THEN WE HAVE GOT TO GET THOSE MEN OUT.

MR. SPOCK?

SPOCK HERE.

TRANSPORTER TECHNICIAN WILSON FOUND INJURED NEAR THE

CAPTAIN'S CABIN.

HE SAYS THE IMPOSTER ATTACKED HIM.

CALLED HIM BY NAME, TOOK HIS HAND PHASER.

UM, ACKNOWLEDGED. CONTINUE THE SEARCH.

WE'VE GOT TO FIND HIM BEFORE HE--

BUT HOW?

APPARENTLY, THIS DOUBLE, HOWEVER DIFFERENT

IN TEMPERAMENT, HAS YOUR KNOWLEDGE

OF THE SHIP, ITS CREW, ITS DEVICES.

THIS BEING THE CASE, PERHAPS WE CAN OUT GUESS HIM BY

DETERMINING HIS NEXT MOVE.

KNOWING HOW THE SHIP IS LAID OUT,

WHERE WOULD YOU GO TO ELUDE A MASS SEARCH?

THE LOWER LEVELS, THE ENGINEERING DECK.

SET AND LOCKED ON BASE CYCLE TO STUN,

NOT TO KILL.

WHAT ABOUT YOUR PHASER, CAPTAIN?

DON'T YOU THINK WE OUGHT TO GET SOME HELP, CAPTAIN?

NO.

I DON'T WANT ANYONE ELSE TO SEE THE--

CAPTAIN, YOU ORDERED ME TO TELL YOU.

MR. SPOCK, IF I'M TO BE THE CAPTAIN,

I'VE GOT TO ACT LIKE ONE.

[ MUSIC ]

YOU CAN'T HURT ME.

YOU CAN'T KILL ME.

YOU CAN'T.

DON'T YOU UNDERSTAND?

I'M PART OF YOU.

YOU NEED ME.

I NEED YOU.

I DON'T NEED YOU.

[ SCREAM ]

[ PHASER BLAST ]

HE'LL BE REGAINING CONSCIOUSNESS SOON.

AND NOT KNOWING WHAT HIS PHYSICAL STATE IS,

I DON'T THINK I'D DARE GIVE HIM A TRANQUILIZER OF ANY KIND.

I THINK WE'D BETTER BIND HIM.

YES. YES. ALL RIGHT.

WHAT'S THE MATTER WITH ME?

JUDGING FROM MY OBSERVATIONS, CAPTAIN,

YOU'RE RAPIDLY LOSING THE POWER OF DECISION.

YOU HAVE A POINT, SPOCK?

YES, ALWAYS, DOCTOR.

WE HAVE HERE AN UNUSUAL OPPORTUNITY TO APPRAISE

THE HUMAN MIND.

OR TO EXAMINE, IN EARTH TERMS,

THE ROLES OF GOOD AND EVIL IN A MAN.

HIS NEGATIVE SIDE, WHICH YOU CALL HOSTILITY,

LUST, VIOLENCE.

AND HIS POSITIVE SIDE, WHICH EARTH PEOPLE EXPRESS

AS COMPASSION, LOVE, TENDERNESS.

IT'S THE CAPTAIN'S GUTS YOU'RE ANALYZING.

ARE YOU AWARE OF THAT, SPOCK?

YES.

AND WHAT IS IT THAT MAKES ONE MAN AN EXCEPTIONAL LEADER?

WE SEE HERE INDICATIONS THAT IT IS HIS NEGATIVE SIDE,

WHICH MAKES HIM STRONG.

THAT HIS EVIL SIDE, IF YOU WILL,

PROPERLY CONTROLLED AND DISCIPLINED,

IS VITAL TO HIS STRENGTH.

YOUR NEGATIVE SIDE REMOVED FROM YOU,

THE POWER OF COMMAND BEGINS TO ELUDE YOU.

WHAT IS YOUR POINT, MR. SPOCK?

IF YOUR POWER OF COMMAND CONTINUES TO WEAKEN,

YOU'LL SOON BE UNABLE TO FUNCTION AS CAPTAIN.

YOU MUST BE PREPARED FOR THAT.

YOU HAVE YOUR INTELLECT, JIM. YOU CAN FIGHT WITH THAT.

FOR HOW LONG?

IF I SEEM INSENSITIVE TO WHAT YOU'RE GOING THROUGH,

CAPTAIN, UNDERSTAND, IT'S THE WAY I AM.

[ WHISTLE ]

CAPTAIN KIRK?

KIRK HERE.

MR. SCOTT, SIR, ON THE LOWER LEVEL

OF THE ENGINEERING DECK.

I FOUND A NEW TROUBLE WITH THE TRANSPORTER.

THE CASING HAS A WIDE GAP RIPPED IN IT.

THE MAIN CIRCUITS HAVE BEEN BURNED THROUGH.

THE ABORT CONTROL CIRCUIT IS GONE ALL TOGETHER.

[ MUSIC ]

CAN YOU GIVE US A STATUS REPORT, CAPTAIN?

TEMPERATURE'S STILL DROPPING.

NOW FORTY-ONE DEGREES BELOW ZERO.

WE'VE LOCATED THE TROUBLE. IT SHOULDN'T BE MUCH LONGER.

DO YOU THINK YOU MIGHT BE ABLE TO FIND A LONG ROPE SOMEWHERE

AND LOWER US DOWN A POT OF HOT COFFEE?

I'LL SEE WHAT WE CAN DO.

RICE WINE WILL DO IF YOU'RE SHORT ON COFFEE.

ENGINEERING DECK, KIRK HERE.

SCOTT HERE, CAPTAIN.

THAT UNIT, SCOTTY, STATUS REPORT?

THE TRANSPORTER UNIT IONIZER, NOTHING MUCH LEFT OF IT, SIR.

HOW BAD IS IT?

WE CAN'T REPAIR IT IN LESS THAN A WEEK.

[ MUSIC ]

CAPTAIN'S LOG, STAR DATE 1673.5.

TRANSPORTER'S STILL INOPERABLE.

MY NEGATIVE SELF IS UNDER RESTRAINT IN SICK BAY.

MY OWN INDECISIVENESS GROWING.

MY FORCE OF WILL STEADILY WEAKENING.

ON THE PLANET, CONDITION CRITICAL.

SURFACE TEMPERATURE IS SEVENTY-FIVE DEGREES

BELOW ZERO, STILL DROPPING.

[ MUSIC ]

[ BUZZING ]

I THINK WE OUGHT TO GIVE ROOM SERVICE ANOTHER CALL.

THAT COFFEE'S TAKING TOO LONG.

[ ELECTRONIC BEEPING ]

ENTERPRISE, THIS IS SULU.

KIRK HERE, MR. SULU.

HOT LINE DIRECT TO THE CAPTAIN.

ARE WE THAT FAR GONE?

I GAVE EVERYBODY THE AFTERNOON OFF.

I'M WATCHING THE STORE.

HOW IS IT DOWN THERE?

OH, LOVELY.

EXCEPT THAT THE FROST IS BUILDING UP.

WE'RE USING HAND PHASERS TO HEAT THE ROCKS.

ONE PHASER QUIT ON US, THREE STILL OPERATING.

ANY POSSIBILITY OF GETTING US BACK ABOARD BEFORE

THE SKIING SEASON OPENS DOWN HERE?

THIS IS SPOCK, MR. SULU.

YOU'LL HAVE TO HOLD ON A LITTLE LONGER.

THERE'S NO OTHER WAY. SURVIVAL PROCEDURES, MR. SULU.

PER YOUR TRAINING PROGRAM, MR. SPOCK.

[ SCREAMING ]

[ BEEPING ]

WHAT HAPPENED?

APPARENTLY, THE BODY FUNCTIONING WEAKENED

DURING THE DUPLICATION PROCESS.

A FACT I FAILED TO CONSIDER.

HE'S NOT DYING?

YES, HE IS.

HELP ME.

HOW CAN HE DIE? HOW CAN I SURVIVE WITHOUT HIM?

I DON'T KNOW, JIM.

DON'T BE AFRAID.

HERE'S MY HAND. HOLD ON.

YOU DON'T HAVE TO BE AFRAID.

I WON'T LET GO. HOLD ON.

YOU WON'T BE AFRAID IF YOU USE YOUR MIND AND THINK.

THINK! YOU CAN DO IT.

THAT'S IT.

JIM, HE IS BACK.

[ MUSIC ]

JIM, YOU CAN USE THAT BRANDY NOW.

IN FACT, I'LL JOIN YOU.

I HAVE TO TAKE HIM BACK INSIDE MYSELF.

I CAN'T SURVIVE WITHOUT HIM.

I DON'T WANT TO TAKE HIM BACK. HE'S LIKE AN ANIMAL.

A THOUGHTLESS BRUTAL ANIMAL.

YET, IT'S ME. ME.

JIM, YOU'RE NO DIFFERENT THAN ANYONE ELSE.

WE ALL HAVE OUR DARKER SIDE. WE NEED IT.

IT'S HALF OF WHAT WE ARE.

IT'S NOT REALLY UGLY. IT'S HUMAN.

HUMAN?

YES, HUMAN.

PART OF WHAT HE IS MAKES YOU THE MAN YOU ARE.

GOD FORBID I SHOULD HAVE TO AGREE WITH SPOCK,

BUT HE WAS RIGHT. WITHOUT THE NEGATIVE SIDE,

YOU WOULDN'T BE THE CAPTAIN. YOU COULDN'T BE.

AND YOU KNOW IT. YOUR STRENGTH OF COMMAND

LIES MOSTLY IN HIM.

WHAT DO I HAVE?

YOU HAVE THE GOODNESS.

NOT ENOUGH.

I HAVE A SHIP TO COMMAND.

THE INTELLIGENCE, THE LOGIC.

IT APPEARS YOUR HALF HAS MOST OF THAT.

AND PERHAPS THAT'S WHERE MAN'S ESSENTIAL COURAGE COMES FROM.

FOR YOU SEE, HE WAS AFRAID,

AND YOU AREN'T.

[ WHISTLE ]

CAPTAIN KIRK?

KIRK HERE.

SPOCK HERE.

WOULD YOU COME TO THE TRANSPORTER ROOM?

WE THINK WE MAY HAVE FOUND AN ANSWER.

COMING.

[ MUSIC ]

WHAT IS IT?

WE FOUND A WAY TO GET THE TRANSPORTER WORKING, SIR.

WE'VE ATTACHED TO SOME BYPASS AND LEADER CIRCUITS

TO COMPENSATE FOR THE DIFFERENCE.

TIED DIRECTLY INTO THE IMPULSE ENGINES.

YES.

THERE SHOULDN'T BE MORE THAN A FIVE-POINT VARIATION

IN THE VELOCITY BALANCE.

I SUGGEST WE SEND THE ANIMAL THROUGH.

CAPTAIN?

YES.

YES, GO AHEAD.

[ DOG GROWLS FEROCIOUSLY ]

I'LL GRAB HIM BY THE SCRUFF OF THE NECK AND HOLD HIM AS LONG

AS I CAN.

DON'T HURT HIM.

IT'S PAINLESS AND QUICK.

THE ANIMAL WILL BE UNCONSCIOUS FOR ONLY A FEW MINUTES.

UH, IF THIS DOESN'T WORK, I DON'T KNOW WHAT WILL.

[ BEEPING ]

ENERGIZE.

REVERSE.

[ BEEPING ]

[ MUSIC ]

THE SHOCK OF PUTTING HIM BACK TOGETHER SEEMS

TO HAVE BEEN TOO MUCH FOR HIM. HE'S DEAD, JIM.

[ MUSIC ]

CAPTAIN'S LOG, STAR DATE 1673.1.

ENTRY MADE BY SECOND OFFICER SPOCK.

CAPTAIN KIRK RETAINS COMMAND OF THIS VESSEL.

BUT HIS FORCE OF WILL RAPIDLY FADING.

CONDITION OF LANDING PARTY CRITICAL.

TRANSPORTER UNIT STILL UNDER REPAIR.

AUTOPSY IN DEPTH. HURRY.

I DON'T KNOW.

THE ANIMAL COULD'VE DIED OF SOME KIND OF SHOCK.

FOR ONCE I AGREE WITH YOU, DOCTOR.

I SAID COULD HAVE, MR. SPOCK.

WE WON'T KNOW UNTIL WE GET A FULL POST MORTEM.

NO AUTOPSY IS NECESSARY TO KNOW THAT THE ANIMAL WAS TERRIFIED,

CONFUSED.

IT WAS SPLIT INTO TWO HALVES AND SUDDENLY THRUST BACK

TOGETHER AGAIN.

THUS SHOCK, INDUCED BY BLIND TERROR.

YES. YES. THAT SOUNDS LIKELY.

IT COULDN'T UNDERSTAND.

YOU CAN.

YOU HAVE YOUR INTELLIGENCE CONTROLLING YOUR FEAR.

GET THE TRANSPORTER ROOM READY.

COULD BE, IF, MAYBE, ALL GUESSWORK SO FAR,

JUST THEORY.

JIM, WHY DON'T YOU GIVE ME A CHANCE TO DO AN AUTOPSY

AND LET SPOCK CHECK OUT THE TRANSPORTER CIRCUITS AGAIN?

THAT SOUNDS-- SOUNDS REASONABLE.

WE SHOULD DOUBLE CHECK EVERYTHING.

AREN'T YOU FORGETTING SOMETHING, CAPTAIN?

NO.

I DON'T THINK I FOR--

YOUR MEN ON THE PLANET SURFACE.

HOW MUCH TIME DO THEY HAVE LEFT?

YES, THAT'S RIGHT, THE MEN.

WE HAVE TO TAKE THE CHANCE, BONES.

THEIR LIVES--

SUPPOSE IT WASN'T SHOCK, JIM.

SUPPOSE THE DEATH WAS CAUSED BY A TRANSPORTER MALFUNCTION.

THEN, YOU'D DIE.

THEY'D DIE ANYWAY.

JIM, YOU CAN'T RISK YOUR LIFE ON A THEORY!

BEING SPLIT IN TWO HALVES IS NO THEORY WITH ME, DOCTOR.

I HAVE A HUMAN HALF, YOU SEE.

AS WELL AS AN ALIEN HALF SUBMERGED,

CONSTANTLY AT WAR WITH EACH OTHER.

PERSONAL EXPERIENCE, DOCTOR. I SURVIVE IT

BECAUSE MY INTELLIGENCE WINS OUT OVER BOTH.

IT MAKES THEM LIVE TOGETHER.

YOUR INTELLIGENCE WOULD ENABLE YOU TO SURVIVE, AS WELL.

WELL, SOMEBODY MAKE A DECISION.

ARE YOU RELINQUISHING YOUR COMMAND, CAPTAIN?

NO.

NO, I'M NOT.

WELL, THEN, WE CAN'T HELP YOU, JIM.

THE DECISION IS YOURS.

MR. SPOCK, READY THE TRANSPORTER ROOM.

BONES, CONTINUE THE AUTOPSY.

[ MUSIC ]

[ WHISTLE ]

CAPTAIN KIRK?

I HAVE A TIE-IN WITH SULU, NOW.

KIRK HERE.

[ WIND BLOWING ]

CAPTAIN K-KIRK, SULU HERE.

ONE HUNDRED SEVENTEEN BELOW-- CAN'T LAST MUCH LONGER.

CAN'T SEE CLEARLY, DOCTOR, TO READ TOP INDICATOR.

THINK THE COLD PENETRATING COMMUNICATOR.

TWO MEN UNCONSCIOUS. NO TIME.

NO-- CAN'T WAIT.

NO TIME.

MR. SULU? MR. SULU?

CAN'T WAIT.

CAN'T LET THEM DIE.

WHAT ARE YOU GONNA DO?

GO THROUGH THE TRANSPORTER, BOTH OF US.

THERE'S NOTHING I CAN DO TO STOP YOU?

IT'S WHAT I HAVE TO DO.

IT'S WHAT I HAVE TO DO, WHAT WE HAVE TO DO.

I WON'T FIGHT YOU ANYMORE.

OH. I FEEL SO WEAK. I'LL BE GLAD WHEN THIS IS OVER.

[ GRUNT ]

[ MUSIC ]

JANICE, HELLO.

CAPTAIN, UH--

YEOMAN, I OWE YOU AN EXPLANATION.

NO--

YES, I DO.

THE TRANSPORTER MALFUNCTIONED. DIVIDED ME.

CREATED A DUPLICATE. THE ANIMAL PART OF ME

CAME TO YOUR CABIN. HE EVEN SCRATCHED ME

TO MAKE US LOOK MORE ALIKE. I'D LIKE THE CHANCE

TO EXPLAIN IT TO YOU.

YOU DON'T MIND IF I COME TO YOUR CABIN LATER?

NO, SIR.

BRIDGE.

NO WORD FROM MR. SULU, SIR.

PREPARE TO LEAVE ORBIT, MR. FARRELL.

WELL?

CAPTAIN!

I GAVE YOU AN ORDER, MR. FARRELL.

BUT WHAT ABOUT--

THEY CAN'T BE SAVED. PREPARE TO LEAVE ORBIT.

YES, SIR.

BUT I THOUGHT WE PLANNED--

I CHANGED MY MIND.

GO BACK TO YOUR STATION, MR. SPOCK.

GRAB HIM.

HE'S THE IMPOSTER.

NO!

MC COY, HE'S FOOLED YOU.

HE ATTACKED HIM.

MR. SPOCK, YOU KNOW WHO I AM.

YOU KNOW WHAT THAT IS.

MR. SPOCK, WHICH ONE?

WHAT DO WE DO?

WE'LL LET THE CAPTAIN HANDLE THIS.

I'M THE CAPTAIN.

ISN'T THAT OBVIOUS? LOOK AT HIS FACE.

REMEMBER THE SCRATCHES?

LOOK HOW HE'S TRIED TO HIDE THEM.

HE WANTS YOU TO THINK THAT HE'S CAPTAIN KIRK.

YOU KNOW WHO I AM.

[ MUSIC ]

YES, I KNOW.

YOU WANT TO KILL ME, DON'T YOU?

FARRELL!

JAMES!

GRAB HIM. HE'LL DESTROY THE SHIP!

I'M THE CAPTAIN!

DON'T YOU UNDERSTAND? I'M CAPTAIN OF THE SHIP!

I'M THE CAPTAIN!

THIS IS MY SHIP!

MY SHIP! IT'S MINE!

[ MUSIC ]

I'LL KILL YOU.

CAN HALF A MAN LIVE?

TAKE ANOTHER STEP, YOU'LL DIE.

THEN, WE'LL BOTH DIE.

PLEASE?

I DON'T WANT TO.

DON'T MAKE ME.

DON'T MAKE ME.

I DON'T WANT TO GO BACK. PLEASE?

I WANT TO LIVE!

YOU WILL. BOTH OF US.

I WANT TO LIVE!

[ MUSIC ]

YOU'LL HAVE TO HOLD ONTO HIM, CAPTAIN.

MR. SPOCK?

CAPTAIN?

IF THIS DOESN'T WORK--

UNDERSTOOD, CAPTAIN.

[ MUSIC ]

MR. SPOCK?

[ BEEPING ]

READY.

[ BEEPING ]

WELL, MR. SPOCK?

[ BEEPING ]

JIM?

GET THOSE MEN ABOARD FAST.

RIGHT AWAY, CAPTAIN.

[ MUSIC ]

SEVERE EXPOSURE, FROST BITE.

BUT I THINK THEY'LL MAKE IT.

HOW DO YOU FEEL, JIM?

HOW?

I'VE SEEN A PART OF MYSELF NO MAN SHOULD EVER SEE.

STATUS REPORT, GREEN.

ALL SECTIONS REPORT READY, SIR.

GOOD.

THANK YOU, MR. SPOCK, FROM BOTH OF US.

SHALL I PASS THAT ON TO THE CREW, SIR?

THE IMPOSTER'S BACK WHERE HE BELONGS.

LET'S FORGET HIM.

CAPTAIN?

THE IMPOSTER TOLD ME WHAT HAPPENED.

OH?

WHO HE REALLY WAS.

AND I'D JUST LIKE TO SAY THAT-- WELL, SIR,

WHAT I'D LIKE TO SAY IS THAT--

THANK YOU, YEOMAN.

[ MUSIC ]

THE, UH, IMPOSTER HAD SOME INTERESTING

QUALITIES, WOULDN'T YOU SAY, YEOMAN?

[ MUSIC ]

THIS IS THE CAPTAIN SPEAKING.

NAVIGATOR, SET IN COURSE CORRECTION.

HELMSMEN, STEADY AS SHE GOES.

[ MUSIC ]
